This
composite Hubble Space Telescope picture shows the location of a newly
discovered moon, designated S/2004 N 1, orbiting Neptune. The black and
white image was taken in 2009 with Hubble’s Wide Field Camera 3 in
visible light. Hubble took the color inset of Neptune on August 2009.

NASA's Hubble Space Telescope has discovered a new moon orbiting the
distant blue-green planet Neptune, the 14th known to be circling the
giant planet.
The moon, designated S/2004 N 1, is estimated to be no more than 12
miles across, making it the smallest known moon in the Neptunian system.
It is so small and dim that it is roughly 100 million times fainter
than the faintest star that can be seen with the naked eye.

Mars Pathfinder was launched on Dec. 4, 1996 at 1:58:07 am EST on a
Delta II rocket. After an uneventful journey, the spacecraft safely
landed on the surface of Mars on July 4, 1997. The first set of data was
received shortly after 5:00 p.m. followed by the release of images at
9:30 p.m.

The Sojourner rover, with three Lewis components, then began
its Martian trek and returned images and other data over the course of
three months.
